External ear flaps. Flipper shape Large foreflippers; fur stops partway down the flipper. Hindflippers can rotate forward under the body so that the fur seal can stand up on all four flippers. Hindflippers are long and narrow and have very very long toes that can be bent. Hindflippers have nails or claws that they use to scratch themselves. Fur is dark and thick; on males there is a thicker area of fur on the neck and Fur head. Fur has two layers, a dense underfur and longer guard hairs. Juveniles and females have a silvery-brown coat which is lighter on the underside of the animal, and lighter cream-colored “cheek patches.” Male fur color is more uniformly dark brown. Pups have black fur at birth. Pups molt into their first silvery-brown coat by October of their first year.

  • Marine Mammals of Hudson Strait the Following Marine Mammals Are Common to Hudson Strait, However, Other Species May Also Be Seen
    Marine Mammals of Hudson Strait The following marine mammals are common to Hudson Strait, however, other species may also be seen. It’s possible for marine mammals to venture outside of their common habitats and may be seen elsewhere. Bowhead Whale Length: 13-19 m Appearance: Stocky, with large head. Blue-black body with white markings on the chin, belly and just forward of the tail. No dorsal fin or ridge. Two blow holes, no teeth, has baleen. Behaviour: Blow is V-shaped and bushy, reaching 6 m in height. Often alone but sometimes in groups of 2-10. Habitat: Leads and cracks in pack ice during winter and in open water during summer. Status: Special concern Beluga Whale Length: 4-5 m Appearance: Adults are almost entirely white with a tough dorsal ridge and no dorsal fin. Young are grey. Behaviour: Blow is low and hardly visible. Not much of the body is visible out of the water. Found in small groups, but sometimes hundreds to thousands during annual migrations. Habitat: Found in open water year-round. Prefer shallow coastal water during summer and water near pack ice in winter. Killer Whale Status: Endangered Length: 8-9 m Appearance: Black body with white throat, belly and underside and white spot behind eye. Triangular dorsal fin in the middle of the back. Male dorsal fin can be up to 2 m in high. Behaviour: Blow is tall and column shaped; approximately 4 m in height. Narwhal Typically form groups of 2-25.

  • Walrus: Wildlife Notebook Series
    Walrus Pacific walruses (Odobenus rosmarus divergens) belong to a group of marine mammals known as pinnipeds (pinna, a wing or fin; and pedis, a foot), this group also includes the seals and sea lions. Walruses are most commonly found in relatively shallow water areas, close to ice or land. In Alaska, their geographic range includes the Bering and Chukchi Seas. General description: Walruses are the largest pinnipeds in arctic and subarctic seas. The genus name Odobenus means “tooth-walker.” Walrus tusks are elongated upper canine teeth both males and females have tusks. Walruses and sea lions can rotate their hind flippers forward to ‘walk’ on them but seals cannot and drag their hind limbs when moving on land or ice. Walruses are large pinnipeds and adult males (bulls) may weigh 2 tons and the females (cows) may exceed 1 ton. Bulls can be identified by their larger size, broad muzzle, heavy tusks, and the presence of numerous large bumps, called bosses, on the neck and shoulders. Food habits: Walruses feed mainly on invertebrates such as clams and snails found on the bottom of the relatively shallow and rich Bering and Chukchi Seas. Walruses find food by brushing the sea-bottom with their broad, flat muzzles using their sensitive whiskers to locate food items. Tusks are not used for finding food. Walruses feed using suction formed by pulling back a thick piston-like tongue inside their narrow mouth. Walruses are able to suck the soft parts out of the shells; few hard parts are ingested. The rejected shells of clams and snails can be found on the sea floor near the furrows made during feeding.

OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig.

  • Ecology of Ringed Seals (Phoca Hispida) in Western Hudson Bay, Canada
    Ecology of ringed seals (Phoca hispida) in western Hudson Bay, Canada by Magaly Vincent-Chambellant A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of DOCTOR OF PHILOSOPHY Department of Biological Sciences University of Manitoba Winnipeg Copyright © 2010 by Magaly Vincent-Chambellant Abstract Recently, Hudson Bay experienced unidirectional trends in temperature, sea-ice extent, time of break-up, and length of the open-water season. Predicted impacts on population dynamics of ice-associated species include habitat loss and shift in prey availability. The ringed seal (Phoca hispida) depends on a stable ice platform with sufficient snow depth and a productive open-water season for reproduction and survival. Evidence of ringed seal sensitivity to environmental variations has been reported, but mechanisms involved were poorly understood. In western Hudson Bay, density, life-history traits, and diet of ringed seals were monitored over two decades, providing an opportunity to understand the effects of climatic variations on the population dynamics of this long-lived carnivore. Ringed seal density was estimated through strip-transect analyses after aerial surveys were flown in western Hudson Bay in late spring during the annual moult in the 1990s and 2000s. During these periods, ringed seals were also sampled from Inuit subsistence fall harvests In Arviat, NU, and ages, reproductive status, percentage of pups in the harvest, body condition, and diet were assessed. Strong inter-annual variations in these parameters were observed, and a decadal cycle was suggested and related to variations in the sea-ice regime.
